Anybody have this problem?
Excessive tire wear on the left front. All my tires are starting to look funny since every time I rotate the tires, that left front gets moved. It looks like the tire is scalloped aroung the edge and if you look from the front, every other tread row is about an 1/8" of an inch lower. Very weird, I even had the dealer do an alignment, still wears funny. Maybe I need a new dealer to take my truck to. Any suggestions?

Thanks,
Craig

 

I dunno, but I cranked my torsion bars up about 1-1/8" and it seems that the outsides wear just a tiny bit more. I think that made it a bit of-camber. Perhaps get an alignment check or a tire warranty?

Yup - exactly the same problem.

Wrangler RT/S? They seem to be terrible for doing this. My F150 is going in for a regular service next week and I'm having the dealer do a complete suspension inspection and then I'll probably throw on some BFG AT's - I don't want to throw new tires on until I can get it confirmed that there is no suspension problem. Last thing I want is to spend a handfull of $$$ and then have the same thing happen.

BTW my RT/S's have only 25,000 miles on them and the wobble road noise from the uneven wear is driving me INSANE!!!!!

 

make sure you have the proper tire pressure... about 35psi...

I had the same problem when I bought my truck... The previous owner had the tires blown up to 50 psi.... made for a rough ride and wore out the tires.

 

Actually the recommended tire pressure on the wrangler LT's is 42 PSI.

Recommended inflation is posted on the driver's side passenger door. (on my supercab anyway)

 

mine says 35 on the door...

I have a 99 SC 4X4 ORP as well??

42 psi is way too much IMHO... :-)

gonna see lotsa cupping..

 

What's your tire size? --- I bet they are P series rather than LT

Mine is not ORP and runs LT245 75R16's

 

yea, they're 265/70R17, Goodyear Wrangler AT/S.

 

I guess thats the difference between the RT's and the AT's - anyway, I guess that the moral of the story is that people should at least check the recommended pressure posted on the vehicle if they are still running the OEM tires.

LT tires, because of their higher load capacity, do run at a higher pressure than the P (Passenger Metric) tires.

 

The tire pressure for the truck and the tire pressure for the tire are two completely different animals. The pressure recommended on the truck sticker is based on the weight and capacity of the truck. That's what you should use unless you feel you need more. The max tire pressure on the side of the tire is recommended pressure when loading the 'tire' to 'it's' max load, which btw, you will probably never reach in a F-150. I have 305/70 16's and run 35 psi all the way around. Seems to be working good.

On a side note, my tires were scuffing the outside edge of both front tires pretty bad. I went and had a free front end alignment (this is covered under warranty for 12/12) and it was toed in waaaayy too much. Don't know if it was from raising the torsion bars or not, but that would be my guess. Just had it done this past weekend so to early to tell if it fixed the problem. I'm gonna have to rotate the tires to tell anyways because the damage is already done on the front ones. Guess I'll watch in the mean time and make sure it doesn't get worse until I rotate.

 

how often do you rotate? Cupping can be caused by many different things, too long inbetween rotations,UNDER inflation (OVER inflation wears the middle of the tire)worn shocks,worn steering components.

unless you use some crazy aftermarket tire and rim set up you should always follow what is on the door jam. And remember that you need to check and adjust your tire pressure every month! Radials can loose 1-5 pounds per month so if you only check them when you rotate say, it's too late! they are under inflated and cupping!!

good luck!

 

Mine are wearing on everyother section of tread on the outside row only. Dealer mechanic said this is normal on GY Wranglers, he said his is the same way. I checked several tires on different brand of trucks and all GY Wranglers and some other brands wear the same way ----- Dodges were all worse than any Fords. My truck is out of warranty and I am sure if it needed an alignment he would have said so (after I suggested an alignment) It may be that the factory alignment specs are for a loaded truck and when the truck always runs empty that spec may cause outer row wear. My tires have about 60% wear left and have 27,000 mi. The results are increased tire noise---when it gets bad I just rotate (about 6,000 mi) by that time the rear tires are worn even again.

 

Thanks for all the info, sorry for posting in the wrong section, I guess I'll have to learn.

I do have Wrangler RT/S, and from what I have read from you guys,I'll just have to rotate the tires a little more often.

Thanks again.

 

Have you ever had the truck aligned? My truck was way out of alignment when I bought it brand new. I cupped the orig. goodyears after about 5k miles. I took it in to get aligned and never had a problem again. I got 45,000 miles out of those tires with perfectly even wear.
